To altwlrom, it may concern:

lie it known that I, ELMER E. MCNTYRE, a citizen of the United States of America, residing at Pittsburg, in thel county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Electrical \Vel ling-Machines, of which the following is a. specification, referenceI be ing had therein to the accompanying drawing.

This invention relates to an electric welding machine and has for its object to provide a machine of such class in av manner as hereinafter set forth for welding together the elements of metallic shea-ves or pulleys, al-

though theinvention is designedI primarily.

for welding the elements of a pulley 'or sheave, such as the spokes, rims, and the hub, yet .it is to be understood that the machine is adapted for use in connection Awith any l purposes wherein it is found applicable.

Further objects of the invention are to provide an electric welding machine which comparatively simple in its construction and arangement, strong, durable, etficient and convenient in its use, readily operated, adjustable for various 'sizes of work,` and comparatively inexpensive to mamifacture. With the foregoing and other lobjects in view, the invention consists of the novel construction, combination and arrangeunint of parts as hereinafter more specifically described and illustrated inthe accompanying drawings, wherein is shov'wn an en'lbodiment of the'inventiou, but it is to be understood that'I changes variations, and modilications can be resorted to, which come within the. scope of the claims hereuntoappended.

The lever 82 is provided with a handle 85.

The operation of the welding is, asffollows: The'hub sections of the'- pulley are clamped together by an insulated clamp,

- the spokes are clamped in position against 'the boss of the hubby an lnsulated clamp 77 so that the ri1n and the run is connected to the spokes by an insulated' clamp. Any suitable clamps capable of performing the function of coupling the elements of the pulley, sheave, or

'wheel together can .be utilized, and it is thought unnecessary to show any form of clamp. The work, z'. e., pulley, sheave, or wheel, is then mounted upon the support 58 after which the 1nechanisn'1'44 is thrown into operation so as toshiftthe piston rod 45 outwardly to cause the support 49 to enter the-hub of thel work and to'further clamp the-'inner ends of the spokes between \the bosses and the .welders The switch 52l is closed whereby the current will be supplied to the welders 47, 48, 56, and 57 and weld the inner ends of the spokes to the hub sections. Prior to the positioning` of the. work upon the support 58, the latter and the support 49 are vertically adjusted to provide for the 'diameter ofthe work. After the inner ends of the spokes are welded to the hub, the current is shut offand the supports 49 and 58 lowered to position the ri'in upon the sectional support in the After the rim has been positioned-dipen the sectional support in the opening 74 of the base 2.1,the InechanislnstB and (i4 are thrown into operation whereby the welders 68 and 7() will be brought into engagement' with the outer ends of a pair of spokes to clamp said outer ends against the rib 12. The elements 75 and 7G Aare then adjusted by the wedge will be held snug-ly againstthe outer ends ofthe spokes. The switch 73 is then closed and the current passes to the Welders 70 through the spokes and' rib to the Welders' (S8 back to the switch. rIhe vouter ends ofthe spokes during the foregoing operati-on, that is to say, on the passage ofthe current will ne welded to the rib l2 of theriin. After one pair of spokes havebeen welded to the rib, the current is shut off and the welders G8 and 70l withdrawn and the pulley is revolved on the supports 49 and 5 8, the Welders 47 and 48,'

5G and 57' being withdrawn sufiiciently to allow of the revolving of the pulley, to poopening 74.

. with the welding of the lnner ends of the spokes to the hub and in this connection wc stated that the pulley is positioned so that such action can be had.
